Another thing an astronaut has to learn about is eating in space. Food is weightless, just as men are.
Food for space has to be packed in special ways. Some of it goes into tubes that a man can squeeze into his mouth. Bite-sized cookies are packed in plastic.
There is a good reason for covering each bite. The plastic keeps pieces of food from travelling in the spaceship. On the earth very small pieces of food would simply fall to the floor. But gravity doesn’ t pull them to the floor when they are out of the plastic in a spaceship. They move here and there and can get into a man’ s eyes or into the spaceship’s instruments. If any of the instruments is blocked, the astronauts may have trouble getting safely home.
As astronauts travel on longer space trips, he must take time to sleep. An astronaut can fit himself to his seat with a kind of seat belt. Or, if he wants to, he can sleep in a sleeping bag which is fixed in place under his seat. But be careful he must put his hands under the belt when he goes to sleep. This is because he is really afraid that he might touch one of controls that isn’ t supposed to be touched until later. [br] The best title of mis article is______.

解析
归纳概括题。文章前两段讲的是太空中“吃”的问题,最后一段讲的是太空中“睡”的问题,所以本篇文章的最佳题目应是A“太空中的吃和睡”。B、C、D都只谈了一个方面,都是片面的。
